Answer:
NO = 10
Step-by-step explanation:
Given a segment joining the midpoints of 2 sides of a triangle, then it is half the length of the third side, that is
18 - 2x =
(9x - 16) ( multiply both sides by 2 to clear the fraction )
36 - 4x = 9x - 16 ( add 4x to both sides )
36 = 13x - 16 ( add 16 to both sides )
52 = 13x ( divide both sides by 13 )
4 = x
Then
NO = 18 - 2x = 18 - 2(4) = 18 - 8 = 10

Answer:
Option (1) will be the answer.
Step-by-step explanation:
Coordinates of the points A and B lying on the line f are (0, 2) and (2, 0) respectively.
Slope of the line f,
![m_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m_%7B1%7D%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
![m_{1}=\frac{2-0}{0-2}](https://tex.z-dn.net/?f=m_%7B1%7D%3D%5Cfrac%7B2-0%7D%7B0-2%7D)
After dilation of line f by a scale factor of 2, coordinates of A' and B' will be,
Rule for dilation,
(x, y) → (kx, ky)
Where k = scale factor
A(0, 2) → A'(0, 4)
B(2, 0) → B'(4, 0)
Slope of line f',
![m_{2}=\frac{0-4}{4-0}](https://tex.z-dn.net/?f=m_%7B2%7D%3D%5Cfrac%7B0-4%7D%7B4-0%7D)
![m_{2}=-1](https://tex.z-dn.net/?f=m_%7B2%7D%3D-1)
Since, ![m_{1}=m_{2}=-1](https://tex.z-dn.net/?f=m_%7B1%7D%3Dm_%7B2%7D%3D-1)
Therefore, both the lines f and f' will be parallel.
Option (1) will be the answer.
